Hi folks... first off, I'm new hear as a poster, but long time lurker. Secondly, I've searched this forum quite extensively, but not found quite the answer to my current problem.

Like quite a few others, I've been running both WeatherLink and Virtual Weather Station (VWS does my WUnderground updates) for quite a few years. I typically get things working with WeatherLink and then use VWS for just about everything else. This has been running on an older Windows XP based desktop. I have a Vantage Pro 2 system and a Weather Envoy with USB data logger (connecting to a USB port on my computer).

I acquired a new Windows 7 based computer (an HP Touchscreen) a few weeks ago and decided it is time to move my weather station software to it.

All data was backed up, WeatherLink (original disk) installed, then upgraded to 5.9.3 (the latest). And I cannot get WL to connect AT ALL. I thought I'd check here to see if anyone has any ideas -- before I submit all of this to Davis. I've also supplied a number of screenshots attachments that will maybe illustrate what I am seeing

Note: when I plug / unplug the USB cable from the data logger, the Ports entry: "Silicon Labs CP210x USB to UART Bridge (COM3)" appears and disappears. The Silicon Labs driver version is 6.3.0.0 (01/10/2011).

Details about my computer are in the 3rd attachment.

Does anyone see anything specific in what I have provided to get past this.

I think that if you have WL usb, try using the usb setting for comm. Select USB, then select 'Auto Detect'. DON'T select 'Serial'. Give that a try and see what happens. Use usb for VWS also, 'Davis Vantage Pro/ Pro2 (USB Interface)'. That is what works for me. Jack

No, when I run both on USB, I don't need VirtualVP. As long as WeatherLink is set to USB, and VWS is set to USB, there 'should not' be a problem. The problem comes when you are running Cumulus, then you have to switch WL, and VWS to 'serial' because Cumulus has an issue with WL usb. Jack

Bill Select 'USB' and when the pop-up comes up, select 'OK' and see what happens. Then select 'OK' when the pop up goes away.( on the communication port window) I use both USB and serial, right now, I'm using serial because I am running VirtualVP and you have to use serial to hook up with Cumulus. Sorry for the wrong info.....Jack
